This knowledge will provide a basis for … Many water treatment plants use a combination of coagulation, sedimentation, filtration and disinfection to provide clean, safe drinking water to the public. LOKESH SAINI 1.1.1. Environmental Engineering-I (Water Supply Engg.) - TE (CIVIL) Course material by PROF S S JAHAGIRDAR, NKOCET, SOLAPUR. A jar test simulates the coagulation and flocculation processes Fill the jars with raw water sample (500 or 1000 mL) – usually 6 jars Adjust pH of the jars while mixing using H 2 SO 4 or NaOH/lime (pH: 5.0; 5.5; 6.0; 6.5; 7.0; 7.5) Add same dose of the selected coagulant (alum or iron) to each jar Coagulation and flocculation are an essential part of drinking water treatment as well as wastewater treatment.
